Railfan Atlas

Though many of us would rather not look at another train once we get done with our daily commutes, others of us revel in the images of railfandom, a subculture of train enthusiasts. One self-professed rail geek, Nick Benson, even went so far as to create the Railfan Atlas, a worldwide collection of Flickr train photos. The images are geotagged, and there’s a heat map that shows the hottest spots for train porn.
